1 answer:
Answer:
80
Step-by-step explanation:
A company selects 50 random packages from which two of them have an incorrect weight. That is to say: 4% of the packages are incorrrect.
Now if the company selects 2000 packages, we could predict that 4% of them could be incorrect. We know that 2000×0.04 = 80.
Therefore, 80 out of 2000 packages are expected to have an incorrect weight.

Answer:
a) x = 18
b) y = 35
c) t = 4.5
Step-by-step explanation:
a) x + x + x = 54
3x = 54
x = 54 ÷ 3
x = 18
b) y/5 = 7
(y/5) × 5 = 7 × 5
y = 35
c) 4t + 6 = 24
4t +6 - 6 = 24 -6
4t = 18
4t ÷ 4 = 18 ÷ 4
t = 4.5
